BEPEATER FOR ROLLING MILLS.

Appneaun mea may 12,

The present invention relates to mechanical repeaters for rolling mills, and has for one. of its objects to provide a devlce of this character adapted to divert a strip from one mill'to a second millout of alignment wlth the first ymill and having provision for permitting the strip to have unrestrlcted movement between the mills after it has entered, the second mill, whereby to enable the loop l0 to vary in length in accordance with vanations in the draft of the mills.

A further object of the invent-lon v-1s to provide in combination with the repeater a twister associated with the receiving end. og

the repeater for turning a strip coming' from the -irst mill through an angle about its longitudinal xaxis prior to the introduction of the Strip into the repeater. y

A preferred embodiment of the inventlon is illustrated in the accompanying drawings,

in which,-

Referring to Figure 1, 2 and 3 designate a'pair of rollin mills for rolling strip. ma terial, such as s elp, .and 4 designates a re- ,peaterjembodying my invention for'divert- '40 ing11 a strip coming from the mill 2 to the Interposed between the receiving Iendof the repeater and the horizontal mill 2 isa twister 5 for'receiving astrip from the rolls 45. of the mill and turnmg' it about its 1ongitudinal axis through any desired angle.- In the construction shown, the receiving twister is designed to turn the strip through an angle of l90-degrees so as to deliver it to the repeater in a vertical position. It will be v"apparent, of course, that the twister may be designed to turn the strip through an other A desired angle, either greater or less t 'an 90 i degrees. By reference to Figures 2 and 3, 1t

will be seen that the receiving twister is constructed of plates and channels providing a 1924. n Serial N0. 712,557.

horizontal mill 3. This twister may be of any -usual construction.

The repeater may comprise a suitable base p'late 11. Riveted or otherwise fastened to this base plate is an angle12 which constitutes one elementof a guidl for guiding a strip from the receiving twister 5 into the delivery twister 10. As shown, the angle 12 is bent into arcuate form. Cooperating with the angle 12 is a movable angle 13 pivotally mounted on the lower ends of rocker arms 14 co'A and a lever 15. Rising from the base plate 11, adjacent the ends of the angle 12, is a pair of standards 16- and 17, and lntermediate these standards is another standard 18. These standards are rigidly secured at their lower ends to thebase plate by means of angles 19, and they are connected ,to each other andto 'the base b bracing members 20 and 21. Journaled in t e upper ends of the standards is a. horizontal rock shaft. 22, upon the opposite ends ofwhich are mounted the yrocker arms 14. The lower ends of the.

rocker arms are pivotally connected to the angle 13 by means of removablepins 23 which extend through spaced ears 24 and 25 riveted to the angle. The standard 16 has a bearing portion 26 intermediate its ends in which is journaled a short horizontal rock shaft 27. This rockshaft is also journaled in another vertical standard 28V spaced from the standard 16 and secured at its lower end to the base plate 11, the standard 28 being positioned outside the angle 12 and cooperating anglev 13. On the inner end of the rock shaft 27 is mounted a rocker arm 29 which is connected by a link 30 to a rocker arm 31 carried by the rock shaft 22'. On the outer Iend of the. rock shaft 27 is mounted an loperating handle 32. plate 11, adjacent the inner side of the angle 12 about midway the ends thereof, is a pair of spaced standards 33 secured at their lower ends tothe base plate by angles 34. The

lever 15v is pivoted between the standards 33 upon a pivot bolt 35 which extends through loo Rising .from the base the upper ends of said standards. Bolted to the upper end of the lever 15 is a number of weights 36. The rock shaft 22 has secured thereto, adjacent-the intermediate standard 18, an arm 37 upon which is mounted weights 38. The angle 13 is braced by an angle 39 which extends parallel to the rock shaft 22 and has its ends secured to the angle 13 adjacent the ends of the lat-ter. This bracing angle 39 prevents the angle 13 from spreadino'.

when the parts are held in the closed position shown in Figure 5 by means of the operating handle 32, the angles 12 and 13 lform between them an arcuate guide passage 40 which registers at one end with the delivery is so constructed that the strip is not subjectend of the passage 6 in the receiving twister 5, and at its other end with the passage' of the twister 10. In this posit-ion of the parts, a strip coming from the mill 2 will pass through the receiving twister 5 and will be guided by the repeater into the delivery twister 10, from whence the strip will pass to the mill 3. After the strip has entered the mill 3, the operating handle may be released, whereupon the angle 13 will bemoved automatically to the open position shown in Figure 5 by the weights 36 and 38. In this open position of the angle 13, the movement of the strip between the receivingand de-I livery twistersis unrestricted, so that after the direction of its course has been changed to divert it from one mill to the other, the strip may assume any length ofloop between the mills which the conditions under which it is being rolled may require. The repeater ed to pinching when the repeater is being changed from the, closed to the open position. The weights 36 and 38 serve to maintain the repeater normally in the open position'. The receiving twister is adapted to effect a desirable cooling of the strip after it comes from the mill 2 and before it enters the repeater.

While we have shown and described a preferred embodiment of the invention, it will be understood that changes may be made in the construction and operation disclosed without departing from the spirit of the invention or scope of the appended claims. It is also to be understood that the word strip as used throughout the specilication 'and Y claims is used as a word of description and not of limitation.
